Research Overview Preclinical · cell & animal
What it is
SS-31 is a synthetic tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2) belonging to the Szeto-Schiller family of mitochondria-targeted peptides. Its alternating aromatic and basic residues allow it to concentrate at the inner mitochondrial membrane, where it associates with the phospholipid cardiolipin. It is supplied as a lyophilized powder.
Preclinical (cell & animal) research themes
Cell-culture and animal studies have used SS-31 to investigate cardiolipin binding, electron-transport-chain efficiency, reactive-oxygen-species production and mitochondrial membrane structure under stress. It is frequently used as a tool compound in models of mitochondrial dysfunction across tissue types.
Why laboratories order it
It is one of the best-characterized cardiolipin-targeting peptides and a common positive-control compound in mitochondrial-bioenergetics assays.
Avenio Bio supplies this compound strictly for laboratory research — not for human or veterinary use, and not to diagnose, treat, cure, or prevent any disease.
Frequently Asked Questions
What form is SS-31 supplied in?
A lyophilized powder in a sealed 10 mg vial with lot number and QR code.
Is there a certificate of analysis for this lot?
The Current Batch box on this page shows the documentation status for the lot currently shipping. When an independent report exists it is linked there and in the COA Library; otherwise the lot is marked COA pending.
How should the vial be stored?
Lyophilized: at -20 °C, protected from light. After reconstitution in the laboratory: 2-8 °C and used within weeks; avoid repeated freeze-thaw cycles.
What research areas is SS-31 associated with?
Mitochondrial bioenergetics, cardiolipin biology and oxidative-stress research in cell and animal models.
What does Dmt in the sequence mean?
2',6'-dimethyltyrosine, a modified tyrosine residue that contributes to the membrane affinity of the peptide.
